In Europe and America, most building glass uses PVB laminated glass. This is not only to avoid injury accidents, but also because PVB laminated glass has the ability to resist seismic intrusion. The interlayer film can withstand continuous attacks from weapons such as hammers and firewood knives. Special PVB laminated glass can also resist bullet penetration for a considerable period of time. Its level of security protection can be said to be extremely high.
Whether the sound insulation effect of modern residences is good or not has become one of the important factors for people to measure the quality of housing. Laminated glass with PVB film can block sound waves and maintain a quiet and comfortable office environment. Its unique function of filtering ultraviolet rays not only protects people's skin health but also keeps valuable furniture, display items and other items at home from fading. It can also reduce the transmission of sunlight and lower the energy consumption for cooling.
The numerous advantages of PVB laminated glass can also bring unexpected good effects when used in home decoration. For instance, many household doors, including those in the kitchen, are made of frosted glass. When cooking rice, the kitchen fumes tend to accumulate on it. If laminated glass is used instead, this problem won't occur. Similarly, large areas of glass partitions at home pose a safety hazard to naturally active children. If laminated glass is used, parents can rest assured.
PVB laminated glass can break safely. It may shatter under the impact of a heavy ball, but the entire piece of glass remains intact, and the broken pieces and sharp small fragments still stick to the interlayer film. Tempered glass requires a considerable impact force to break. Once it breaks, the entire piece of glass shatters into countless fine particles, leaving only a few broken pieces in the frame. Ordinary glass shatters easily upon impact, presenting a typical breaking condition and generating many long, sharp-edged fragments. When laminated glass breaks, mirror-toothed fragments surround the opening, and there are many glass fragments left around the penetration point. The lengths of the broken metal wires vary.
The rapid development of urbanization and the real estate industry has led to a significant increase in the demand for PVB laminated glass. At present, the urbanization construction in our country is advancing at an unprecedented pace. The increase of small cities, the renovation of large and medium-sized cities, and the construction of urban infrastructure have become important driving forces for investment demand and economic growth in our country, and at the same time have generated a strong demand for PVB laminated glass. In addition, China's real estate industry is in a stage of rapid development. In the first quarter of 2005, China's real estate investment increased by 26.7%, continuing to maintain a high growth rate. With the rapid development of China's real estate industry, the decoration and renovation industry in China has also advanced in recent years, with its total output value increasing at a rate of about 20% annually. The prosperity of the building decoration and renovation industry has greatly driven the consumption of building decoration materials. It is estimated that the demand for PVB laminated glass will exceed 15 billion yuan in the next five years, thus becoming an important value-added factor that cannot be ignored in the development of the national economy. From the perspective of consumption structure, among the five major consumption hotspots of housing, automobiles, tourism, education and information and news services, housing is the primary growth point at present. From the perspective of market space, the rapid growth of real estate investment will support a steady increase in the demand for PVB laminated glass.
